How to disable UITextField editing but still accep

Question

I'm making a UITextField that has a UIPickerView as inputView. Its all good, except that I can edit by copy, paste, cut and select text, and I don't want it. Only the Picker should modify text field.

I've learned that I can disable editing by setting setEnabled or setUserInteractionEnabled to NO. Ok, but the TextField stop responding to touching and the picker don't show up.

What can I do to achieve it?

Answer 1

I used :

[self.textField setEnabled:NO];

and its work fine

Answer 2

This workaround works. Put a transparent UIView above the text field and implement the following code:

- (void)viewDidLoad
{
 [super viewDidLoad];

   UILongPressGestureRecognizer *press = [[UILongPressGestureRecognizer alloc]             initWithTarget:self action:@selector(longPress)];
[transparentView addGestureRecognizer:press];
 [press release];
  press = nil;
}

-(void)longPress
{
   txtField.userInteractionEnabled = NO;
}

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
   txtField.userInteractionEnabled = YES;
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
  [txtField becomeFirstResponder];
}
